Indiana's Great Lakes Water Quality Agreement (GLWQA) Domestic Action Plan (DAP) for the Western Lake Erie Basin (WLEB)

Welcome to Indiana's DAP

Indiana’s Great Lakes Water Quality Agreement (GLWQA) Domestic Action Plan (DAP) to reduce phosphorous to the Western Lake Erie Basin (WLEB) is the product of a dedicated Advisory Committee comprised of representatives from different stakeholder sectors and led by the Indiana Department of Environmental Management (IDEM). Founded on the principle of adaptive management, this DAP is a dynamic document acknowledging that phosphorous loading in particular, and nutrient pollution in general, is a very complex problem caused by point and nonpoint sources across all sectors, which requires a multi-dimensional solution.
